Quick Technical Amp Q

Was doing some messing around when I found out I accidentally borrowed a friend's boost pedal. That plus another boost and light drive later... Glorious fuzzy break up.

Anyways, something odd occurred. I turned down all the controls on my tremolo except the volume which I peaked, so it basically boost. I got the EHX boost peaked as well before the trem. Added some reverb and played. However, when I stop suddenly, the reverb AND the low hum dissapear fpr a second and a half before returning.

Doesn't seem like a problem, but I'm curious what's going on.

you load up a pile of cheaply made gadgets and weir interactions occur... you have an LFO in there even if its not effecting the audio its always on and LFOs have strange itneractions with excessive gain stages of which you have plenty, there's typically some filtering or gating in any LFO circuit that's always on to prevent the oscillator from thumping in time when you aren't playing and that could also be the culprit. These are the perils of using lots of effects.

Odd... It was just two pedals.

You know, I've been thinking lately about these pedals and I think I might start selling a few. I already decided that damned Melo-Verb needs to go as well as the HT-Dual. I'm thinking maybe one low-gain overdrive (Walrus Audio Messner), Ernie Ball MVP, same delay I have, and probably replace the old Digitech 'verb with something more... Singular, I guess. I find myself always defaulting to the plate mode and the sound is alright, but a change of sound would be nice.

but how much circuitry is in those pedals? and did you have them all maxed out? you said 'boost'

I dunno, I just assumed you had your whole board hooked up too... try letting the ac4 do more of the heavy lifting, you would be surprised what its capable of in hot mode as long as you don't dial the master volume full back to bedroom wanker.

Well, the EHX Boost should be basic in circuitry. However, the Melo-Verb may be the problem here. The Tremolo side most likely has a ton of circuitry. However, it has an Intensity and Volume knob. So, if I turn the Intensity to 0, no tremolo. That leaves me with a volume knob that can basically boost while any other controls are rendered useless. Keep in mind it has a reverb side, so yes. A lot of circuitry in one pedal.

Oh right, hot mode doesn't go too hot, but a little bit of gain from a low-gain overdrive makes it go batshit insane. Love the way this amp interacts with drives.

doesn't get that hot? try turning the treble all the way down and gunning the gain. In hot mode the ground on the tonestack is lifted minimizing the effect of the treble control, however it DOES act as a gain control for the mids, by turning it all the way down you max midrange gain and its a SUBSTANTIAL boost compared to hot mode with the treble above 2ish

It's like a soft crunch if that is actually a thing. I've yet to tet this with a good amount of volume, so don't take my word for it.

Also, I just thought of something. If you put a boost before an overdrive, the overdrive will be the main determiner of volume going into the amp, right? I was thinking this because I realised that a clean boost before an overdrive might do more gain increase than actual volume boosting, but I'm not entirely sure.

sort of... depends how hard the clipping (and therefore compression) of the drive is.... a softer drive or a tube pedal will be comdination of boost gain, drive gain and drive output as well as amp controls all working in sympathy to produce clipping at different circuit points as well as to create a composite volume.... hard to explain, read a book
